Vedclass · Answer

(A) Water lily is a floating hydrophyte. In such plants,the leaves float on the surface of the water. If stomata were present on the lower surface,they would be in contact with water,which would hinder the process of gaseous exchange. Therefore,to facilitate transpiration and gaseous exchange,stomata are restricted to the upper surface of the leaf only.
